Inter-hemispheric coherence (IHC) is one of the electroencephalography (EEG) parameters that measures synchronization of oscillations originating from brain regions of different hemispheres and thereby the functional connectivity between them. We know that object discrimination is associated with transient increase in IHC. In this study we will interfere with the transient IHC that is associated with midline object discrimination by using rhythmic repetitive transcranial magnetic stimulation (rTMS).
